A simple self-centring jig for cutting mortises for door locks. The driveshaft accepts 1/4inch shank router bits or Porter Cable style mortise cutters. Simply attach your drill to the shaft to run it; definitely not for use with routers.
Maximum depth of cut is 150mm and the sliding length is variable by adjusting clamping heads vertically. The height gauge hooks on top of a door or it can be inverted to set the unit at a pre-set height over the floor. Power drill and cutting bits not included.
